一个自动清除日期目录的shell脚本，自动清理指定日期格式的linux目录，删除基于日期来创建的文件夹。 在linux系统中，有很多基于日期来创建文件夹，甚至还会有层级很深的子文件夹，对于这些日期文件整个移除，通过find结合rm或delete删除，费时费力。
使用以下shell脚本，可以嵌入到其他脚本，也可直接调用，用于清除日期目录。
[root@itnetcn ~]# more purge_datedir.sh
#!/bin/bash # Author: Leshami # Blog : http://blog.csdn.net/leshami RemoveDir=/log/hotbak/physical dt=`date +%Y%m%d -d "3 day ago"` for subdir in `ls $RemoveDir`; do if [ "${subdir}" \< "${dt}" ]; then rm -rf $RemoveDir/$subdir >/dev/null echo "The directory $RemoveDir/$subdir has been removed." fi done
